Abstract
In the case of fiber products, flame-retardant properties can be achieved by applying a polyethylenimine and a phosphonic acid to the fiber products or to precursors thereof. The fiber products may be sheet-like textile structures in the form of woven fabrics or they may be yarns or fiberboards. The precursors of the fiber products may be aqueous fiber suspensions which are further processed to give paper or fiberboards.
